Lately I encountered some issues with apache2's proxy server.
On yesterday evening not knowing what it did.
When I tried accessing my webhost this evening it was very slow and unstable.
I checked the access log and saw alot of IP addresses were trying to connect to my server.
After some searching I found out
ProxyRequests On was causing the issue and I disabled it.
Now my local proxies are working just fine and everything works as it should.
There are just 2 question I'd like an answer to:
ProxyRequests On do exacly and how did all these ip addresses know there was a proxy server running on my server?
